    a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable

    granted to You under this License for that Work shall terminate as of the

<p><strong><a name="redistribution">4. Redistribution</a></strong>. You may reproduce and
    distribute copies of the Work or Derivative Works thereof in any medium,
    with or without modifications, and in Source or Object form, provided that
    You meet the following conditions:</p>
<ol style="list-style: lower-latin;">
    <li>You must give any other recipients of the Work or Derivative Works a

    <li>You must retain, in the Source form of any Derivative Works that You

        the Source form of the Work, excluding those notices that do not pertain to
        any part of the Derivative Works; and</li>

    <li>If the Work includes a "NOTICE" text file as part of its distribution,
        then any Derivative Works that You distribute must include a readable copy
        of the attribution notices contained within such NOTICE file, excluding
        those notices that do not pertain to any part of the Derivative Works, in
        at least one of the following places: within a NOTICE text file distributed
        as part of the Derivative Works; within the Source form or documentation,
        if provided along with the Derivative Works; or, within a display generated
        by the Derivative Works, if and wherever such third-party notices normally
        appear. The contents of the NOTICE file are for informational purposes only
        and do not modify the License. You may add Your own attribution notices
        within Derivative Works that You distribute, alongside or as an addendum to
        the NOTICE text from the Work, provided that such additional attribution

        <br/>
        <br/>
        You may add Your own copyright statement to Your modifications and may
        provide additional or different license terms and conditions for use,
        reproduction, or distribution of Your modifications, or for any such
        Derivative Works as a whole, provided Your use, reproduction, and
        distribution of the Work otherwise complies with the conditions stated in
        this License.
    </li>

</ol>

<p><strong><a name="contributions">5. Submission of Contributions</a></strong>. Unless You
    explicitly state otherwise, any Contribution intentionally submitted for
    inclusion in the Work by You to the Licensor shall be under the terms and
    conditions of this License, without any additional terms or conditions.
    Notwithstanding the above, nothing herein shall supersede or modify the
    terms of any separate license agreement you may have executed with Licensor
    regarding such Contributions.</p>
<p><strong><a name="trademarks">6. Trademarks</a></strong>. This License does not grant
    permission to use the trade names, trademarks, service marks, or product
    names of the Licensor, except as required for reasonable and customary use
    in describing the origin of the Work and reproducing the content of the
    NOTICE file.</p>
<p><strong><a name="no-warranty">7. Disclaimer of Warranty</a></strong>. Unless required by
    applicable law or agreed to in writing, Licensor provides the Work (and
    each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT
    WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including,
    without limitation, any warranties or conditions of TITLE,
    NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You
    are solely responsible for determining the appropriateness of using or
    redistributing the Work and assume any risks associated with Your exercise
    of permissions under this License.</p>
<p><strong><a name="no-liability">8. Limitation of Liability</a></strong>. In no event and
    under no legal theory, whether in tort (including negligence), contract, or
    otherwise, unless required by applicable law (such as deliberate and
    grossly negligent acts) or agreed to in writing, shall any Contributor be
    liable to You for damages, including any direct, indirect, special,
    incidental, or consequential damages of any character arising as a result
    of this License or out of the use or inability to use the Work (including
    but not limited to damages for loss of goodwill, work stoppage, computer
    failure or malfunction, or any and all other commercial damages or losses),
    even if such Contributor has been advised of the possibility of such
    damages.</p>
<p><strong><a name="additional">9. Accepting Warranty or Additional Liability</a></strong>.
    While redistributing the Work or Derivative Works thereof, You may choose
    to offer, and charge a fee for, acceptance of support, warranty, indemnity,
    or other liability obligations and/or rights consistent with this License.
    However, in accepting such obligations, You may act only on Your own behalf
    and on Your sole responsibility, not on behalf of any other Contributor,
    and only if You agree to indemnify, defend, and hold each Contributor
    harmless for any liability incurred by, or claims asserted against, such
    Contributor by reason of your accepting any such warranty or additional
    liability.</p>
